given array of length n, how select random index based on current time. wanted generate random integer 0 n based on current time. possible mathematically? you can seed random number generator derived value time() : mt_srand(time() / 30 / 60); // reseed every 30 minutes echo mt_rand(0, n); without random number generator can use modulo: echo (time() / 30 / 60) % n; note mt_rand() output may include n whereas module version doesn't.

i never worked type aliases, concept seems useful feature adding semantics on same-typed objects , defending common typos. let's say, there void foo(float volume, float weight) . it's ok if it's invoked this: foo(v, m) , foo(m, v) not obvious typo. void process(iterable<file> javapath, iterable<file> classpath) can use case. unfortunately there no type aliases in java, , workarounds true overkill: aggregating single field class (boxing primitive object; object in object having reference; more complicated serializing/deserializing rules) extending 1 class 1 (like how create variable type alias in java - impossible primitives; classes may final or have inaccessible constructor). so both of them have drawbacks , runtime/performance cost. as far can see, in java, runtime-based "type aliasing" might replaced compile-time checks, @notnull , @nullable processed. there static type-alias checkers/apt tools featuring support constructions void ...
